HOWARD c. FREY, or iunrnnwoon, NEW .InnsEY CUR-B PIPE Application `filed February 27, 193i. Serial No. 518,838.

This invention relates to certain new and useful improvements in sewer drain or culvert pipe'construction and embodies, among other characteristics, supporting elements of a nature designed to prevent 'turning or independent distortion of the pipe sections after same have been connected.

An additional object of the invention consists in the arrangement of passages within the supporting elements for the accommodation of mortar, cement or the like whereby the pipes may be held suspended beneath si dewalks, curbs and the like although the ground beneath the pipes may have settled to an appreciable extent.

More specifically stated the supporting elements may be tapered longitudinally thereof inr oppositely disposed relation to that of the longitudinal Acenter of the pipe whereby the supporting elements may dispose the outer edges thereof parallel to the exposed surface of the sidewalk or curb and yet permit disposing of the pipe at a desired pitch to facilitate drainage.

With the above and other objects in view, the invention further consists of the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings:

Figure l is a longitudinal sectional view taken through the present invention and illustrative of the particular relationship of the supporting elements with the curb and pipe.

Figure 2 is a sectional view taken on line 2--2 of Figure l.

Figure 3 is an end elevation of the form of pipe used at the curb.

Figure i is a top plan view of the curb type of pipe.

Figure 5 is a side elevation of a forni of pipe to be utilized beneath sidewalks.

Figure 6 is afragmentary side elevation of a modified form of the invention combining in one piece the curb and sidewalk pipes.

Figure 7 is a fragmentary top plan view of the Figure 6 modification.

Referring to the drawings in detail where- .in like characters of reference denote corresponding parts, the reference character 10 indicates generally a form of pipe capable of being used for culverts, sewers and the like but in the'pres'ent instance, Afor purposes of' illustration only,same is shown and will be 55 described as a drain pipe for carrying off surface drainage from dwellings to the gutters in the streets. Said pipes may be of castiron, terra cotta or the like and provided with bells ll to fascilitate accommodation of thei ce reduced ends l2 of complemental pipes in the usual manner. is understood from the illustrations of the invention in Figuresl and 4 of the dra-wings, the outermost or discharge end of the curb form of pipe l() is u.) on a bias in conformity to the shoulder portion or rise of the curb from the bottom of the gutter, as indicated at 13. A plate niember 14, carried by the pipe and extended upwardly therefrom in alignment with that of To the aforementioned extremity and the outer suriacev of the curb, will hold back quantities ofthe cement, motar or other plastic compositions used to cement the pipe in place at the i time the curb yis molded. Supporting ele- Y.; ments l5, carried by and laterally extending from the spaced outer surface of the pipe and falling short of extending the entire width of the curb construction, are apertured, as at 16, to facilitatesaccommodation of appro- 5f.: priate portions of vcement or other plastic composition yto maintain said pipe against displacement even though the earth beneath the pipe may have settled or fallen away from the under surface of the pipe to an ap- S51 preciable extent. The ysupporting elements linay be of any size and number, straight, inclined or pitched, in accordance with the particular design and proportions of the curb construction.

ln instances of the above character where sidewalks are arranged in close proximity to the curbs, the next succeeding length or section of pipe, and as indicated at `12, is provided with elongated spa-ced laterally extending supporting elements 17 arranged after the'manner of the supporting members l5 upon the outer surface of the pipe. The outer side edges of the supporting elements or fins 17 are inclined in different directions upon lim' opposite sides of the pipe and each instance out of parallelism with the median center of the pipe section 12 whereby said tapered may be arranged parallel to the outer surface of the sidewalk and yet the pipe 12 may be arranged at a pitch or angle to permit drainage. The su portin elements or fins 17 are also rovi ed wit passages or openings extende transversely therethrough Within and through which suitable quantities of the cement may be forced or purged during the construction of the sidewak whereb j the pipe section 12 may be held against displacement by the sidewalk incident to the settlement of earth beneath the under surface 0f.. ew..

1. e plate 14., carried upon the outermost or diiithtt e end of the curb pipe 10, will prevent tg gutter construction from cracking orA chipping and materially strengthen the of the supporting elements or fins .15. 'The particular angle, inclination or angle of bias assumed by the outermost or ge end of the pipe 10 when arranged and in al' ment with the outer suriaiggofthe curb will fix or predetermine the r ,y nt of the entire chain or assemblage gbr drainage purposes.

j. e modification of the invention disclosed in Figures 6 and 7 of the drawin embodies the characteristics set forth for t e form of invention described and illustrated in F ig- 11.1368 l t0 5 inclusive but differentiates therefrom in that the outer edges of the Ens 17 therefor are not tapered longitudinally thereof but are disposed throughout the major portions of their lengths in parallelism to the median center of the immediate pipe and as g e in Fig-"are 7 of the drawings, the en of said fins are sli htly curved w ereby the corners or of t e cement used in the com nsition of t e curbor sidewalk .will not be 'iped olf.

.Alt ough I have shown and described the i prsent invention as having special a plication Yu n sidewalks, sewers and the ike, it is obviously apparent that the invention may be employed to advantage in other instances, too nlmerous to mention, without departing from the spirit of the invention. The invention is susceptible of various ch in its form, proportions and minor detai of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

2. A drain pipe construction for use at curbs and positioned with relation thereto during the formation thereof comprising Va plurality of equally spaced laterally extending supporting elements outstanding from the pipe adjacent the curb, and said supporting elements each having a plurality Vof assages extending transversely therethroug to accommodate portions of the curb composition to retain the pipe against displacement.,

3. A drain pipe construction for use at curbs and positioned with relation thereto during the formation thereof comprising a plurality of angularly disposed supporting elements outstanding from the pipe adjacent the curb, said supporting elements and each havin passages extending transversely theret rough to accommodate portions of the curb composition to retain the pipe against displacement, and a plate carried by said pipe at the discharge end thereof projecting in a plane with the adjacent surface of the curb to fix the pitch of the pipe.

4. A drain pipe construction for use at sidewalks and positioned with relation thereto during the formation thereof comprising a plurality of spaced supporting elements outstanding from the pipe, said supporting elements having the outer edges inclined in oppositely disposed relation to that of the median center of the pipe to dispose said edges in parallelism to the upper surface of the sidewalk and locating of the pipe at a suitable drainage pitch, and each of said supporting elements having passages extending transversely therethrough for the accommodation of portions of the sidewalk composition to retain the pipe against displacement.

In testimony whereof I afiix my signature.
